[Multipolar electrical stimulation of the olfactory bulb as a model for studying spatial basis of olfactory coding].
Low-intensity electrical stimulation of the olfactory bulb through a set of spatially distributed electrodes was used as a model in order to study the spatial basis of the olfactory coding, in rats. The results indicate that this multipolar stimulation can serve as a conditional stimulus in a learned aversion paradigm; in addition, water-deprived animals displayed high ability to discriminate and memorize various combinations of electrode positions paired with differently palatable solutions.
